💡 How to pick case fans
What to look for:
  • 120mm most common, 140mm moves more air quieter
  • Higher CFM = more airflow, higher dBA = more noise
  • Static pressure fans for radiators, airflow fans for cases
💰 Two intake + one exhaust is a solid baseline for positive pressure

★★★★★Quiet, Cool Upgrade for my Fractal Design Meshify C
To summarize my points before going into details: Pros: + Aesthetically pleasing for my build, white matches the RGB lighting on motherboard and front fans and LED strip + much quieter tone compared to stock Fractal Design case fan + variety of color options for rubber mounts + Strong airflow out of case now + PWM fan compared to old Fractal Design DC 3-pin fan Cons: - High price for fans - short cables - Sort of difficult to mount with screws For more in depth review: I love these fans. I'm officially a "fan" of Noctua fans (HA bet you didn't expect the puns in this review). From my testing, I paired this with another Noctua fan that I replaced on my Cryorig H7 CPU Cooler. I noticed a 3-5 Celsius drop on the CPU. I attribute that to this fan working well with the CPU fan that was also replaced with a Noctua fan. One pushes hard on the cooler tower and this fan gets large amounts of air flowing out of the case. The fan hardly makes any noise compared to the old Fractal Design case fan. It is a much lower tone. I also love that this is a PWM fan compared to the DC 3-pin fan that the Fractal Design fan was. This offers much more variability and control over the fan's RPM. The main downside I found was screwing in this fan. It seems a bit more difficult for some reason. The provided screws did not work for my case, so I used the screws that came with the case rather than the ones that came with the fan. I also put two sets of rubber mounts on both sides of the fan because it was going to be against the metal of the case and I wasn't sure if that would case vibration noise. Overall, very pleased with this product and the static pressure version of this fan. Highly recommend!

★★★★★Amazing quality!
The perfect fan for a heat sync/radiator. Super quiet and reliable. My only gripe is the chroma variants don’t come with all the accessories like the regular fans. But that’s nitpicking because they are usually not needed anyway.

★★★★★AV Cooling System Application
I created a system to provide cooling for an AV cabinet in a closet. Components include Aventage, Emotiva and Oppo. The cooling equipment used includes: 1. Noctua Fans (3) (model# NF-S12A PWM) 2. Noctua Fan controller (model# NA-FC1) 3. Noctua Extension cables (model# NA-SEC1) 4. Cablemod's molex to SATA cable (model# CM-CAB-MSAP 45KK-R) 5. Coolerguys AC power adaptor (110V AC to DC 12V Power Supply with 4 pin Molex) The fans are laid flat on top of the receiver and amplifier pulling air up through the units. Of course, the anti-vibration corner pieces protect the AV equipment and prevent the fans from moving around. There is approximately 4" between the top of each AV component and the shelf above. This seems to allow sufficient air circulation. All Noctua components were packaged nicely and functioned perfectly out of the box. Connections are solid. Using the fans full speed, they are very quiet and are effective in keeping the components at less than 82F degrees. The Noctua Fan Controller is tiny -- about the size of a man's thumb. When setting up the system, I reached out to Noctua for some technical assistance. They were prompt and provided excellent guidance on connecting the power supply to the speed control (Cablemod's connector). The Cablemod's cable has solid connections and functions well. The only thing that would be nice is an outer sheath to keep all four wires together for a cleaner appearance. The Coolerguys AC power adaptor appears well made and functions well to power the three fans. Overall, the system has been running for about 1 month and I am quite satisfied with each of the components and would recommend them to anyone looking for an effective cooling system for an AV cabinet.

★★★★★One of the best exhaust fans
If you have an exhaust area on your pc case that has large openings this is the fan to put there. Will move a bunch of air while barely making any noise. On my pc case (Lian li a3) there is only one exhaust slot so this fan works perfectly. However if you have a case with multiple exhaust/large opening areas. Putting multiple of this fan might get pricey!

★★★★★Amazing fan
Amazing fan. Absolute quite. Be careful with the model tho, this model is not for pressure work.
